Answer:
x = 45
Step-by-step explanation:
Well here's what we know:
2x + 45 + x = 180
Solve from there:
3x = 135
x = 45
You can plug it back in to check:
2(45) + 45 + 45 = 180
90 + 80 = 180, so it checks out :)
Surface area of cylinder = 2 x pi x r x h + 2 x pi x r*2
So 2 x pi x 4 x 11 + 2 x pi x 4*2 = 376.99
Answer:
Nicole should take 13 1/8 cups of snack mix.
Step-by-step explanation:
If a serving size is 7/8 and Nicole wants to take 15 serving sizes (15 7/8's), then we must multiply 7/8 by 15:
15 × 7/8
Write 15 over 1 (15 = 15/1) to make the calculations easier:
15/1 × 7/8
Multiply the numerators and denominators separately:
15 × 7 / 1 × 8
105 / 8
Instructions don't say you have to do this but I will convert this improper fraction into a mixed number:
105/8 = 13 1/8
Answer:
a
Step-by-step explanation:
y = 3x - 7 → (1)
4x - 5y = - 20 → (2)
substitute y = 3x - 7 into (2)
4x - 5(3x - 7) = - 20
4x - 15x + 35 = - 20
- 11x + 35 = - 20 ( subtract 35 from both sides )
- 11x = - 55 ( divide both sides by - 11 )
x = 5
substitute x = 5 into (1)
y = 3(5) - 7 = 15 - 7 = 8
solution is (5, 8 )
Answer:
The answer is (-16.6)
Step-by-step explanation:
y/2 ≥ -8.3
y ≥ (-8.3) × 2
y ≥ -16.6
Thus, The value of y is (-16.6)
